PCM1789 Datasheet

PCM1789 Audio Digital-to-Analog Converter

The PCM1789 is a high-performance, single-chip, 24bit, stereo, audio digital-to-analog converter (DAC) with differential outputs. The two-channel, 24-bit DAC employs an enhanced multi-level, delta-sigma (ΔΣ) modulator, and supports 8 kHz to 192 kHz sampling rates and a 16-, 20-, 24-, 32-bit width di.
